FIELD

This disclosure provides a new and distinctive soybean variety,‘G03-1187RR’.

BACKGROUND

Soybean (Glycine max), is an important and valuable field crop. The USDACrop Reporting Service has reported that over 94% of U.S. soybeanacreage was planted Roundup Ready® soybean cultivars in 2008. In thesoutheastern USA soybean growers prefer MG VII or MG VIII soybeancultivars. Plant breeders continually develop stable, high yieldingsoybean varieties that are agronomically sound, for example to maximizethe amount of grain produced on the land used and to supply food forboth animals and humans. To accomplish this goal, soybean breedersselect and develop soybean plants having one or more desired traits thatresult in superior varieties. These desired traits can include higherseed yield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, better agronomic quality, resistance toherbicides, and improvements in compositional traits.

SUMMARY

The present disclosure relates to a new soybean variety, ‘G03-1187RR’.This new variety is a late Maturing Group (MG) VII (Relative Maturityabout 7.9), glyphosate tolerant, and resistant to many pests that affectsoybeans, including southern, peanut and Javanese root-knot nematodes,race 3 of soybean cyst nematode, and stem canker. ‘G03-1187RR’ also hasimproved seed yield when compared to existing late MG VII Roundup® Readycultivars. Thus, the new variety is adapted to areas of the (such as thesouthern USA) that commonly grow MG VII soybean cultivars and to areasthat are known to have or expected to have damaging levels of thesouthern, peanut, and Javanese root-knot nematodes, race 3 of soybeancyst nematode, and/or stem canker.

A deposit of the new soybean variety ‘G03-1187RR’ has been made with theAmerican Type Culture Collection (ATCC), 10801 University Blvd.,Manassas, Va., 20110. The date of deposit was Jun. 6, 2012. The depositis intended to meet all of the requirements of 37 C.F.R. §§1.801-1.809.The accession number for those deposited seeds of the new soybeanvariety ‘G03-1187RR’ is ATCC Accession No. PTA-12952. The deposit willbe maintained in the depository for a period of 30 years, or 5 yearsafter the last request, or for the effective life of the patent,whichever is longer, and will be replaced if necessary during thatperiod. In one embodiment, the disclosure provides soybean seeddeposited as ATCC Accession No. PTA-12952, as well as bulk soybean seedcontaining such seeds. The plant rows selected to create the initialbreeder seed of ‘G03-1187RR’ were all uniformly resistant to glyphosateat the labeled rates for Roundup Ready® soybeans. All seed increases of‘G03-1187RR’ received an application of herbicidal rates of the Roundup®herbicide.

Resistance orsensitivity to javanese root-knot nematodes is based on a disease scorefrom 1 to 5 comparing all genotypes in a given test. The score is basedon a count of the number of javanese root-knot nematode galls found onthe roots of a plant. A score of 1 indicates there are few galls on theroots. The scores range to a score of 5 which indicates there are manygalls.

Lodging: The visual rating of the uprightness of the plants. The scoreis based on the average of the plants in a plot with a score of 1 to 5,with a score of 1 indicating all plants are erect, and a score of 5where over about 80% of the plants in a plot are prostrate.

Maturity date: The evaluation of plants considered as mature when about95% of the pods have reached their mature color.

Peanut Root-knot Nematode: A plant pathogenic nematode (Meloidogynearenaria) that can result in the presence of galls on roots.

A score of 1 indicates there are few galls on theroots to a score of 5 which indicates there are many galls.

Soybean cyst nematode (SCN): A plant-parasitic nematode (Heteroderaglycines) of the soybean (Glycine max). SCN infects the roots ofsoybean, and the female nematode eventually becomes a cyst. Infectioncauses various symptoms that can include chlorosis of the leaves andstems, root necrosis, loss in seed yield and suppression of root andshoot growth. SCN field populations vary in their abilities tosuccessfully develop and reproduce on a set of four differential soybeanlines that differ genetically in their resistance to SCN. Thesedifferent populations are referred to as SCN races and are given numberdesignations. There are currently 16 possible reaction combinations and,thus, 16 potential SCN races. At least 12 different races have beenreported in the United States, with race 3 the most common in Georgia.Resistance or sensitivity to SCN is based on the presence (sensitive) orabsence (resistance) of cysts of SCN.

Stem Canker: A fungus (Diaporthe phaseolorum) that causes diseases inplants, including soybeans. Resistance or sensitivity to stem canker isranked based on a visual disease score from 1 to 9 comparing allgenotypes in a given test. The score is based on the number of deadplants caused by stem canker. A score of 0 indicates no dead plants.Visual scores range to a score of 9 which indicates severe symptomsresulting in 90 to 100% dead plants.

Transgene. A gene or genetic material that has been transferred into thegenome of a plant, for example by genetic engineering methods. Exemplarytransgenes include cDNA (complementary DNA) segment, which is a copy ofmRNA (messenger RNA), and the gene itself residing in its originalregion of genomic DNA. In one example, describes a segment of DNAcontaining a gene sequence that is introduced into the genome of asoybean plant or plant cell. This non-native segment of DNA may retainthe ability to produce RNA or protein in the transgenic plant, or it mayalter the normal function of the transgenic plant's genetic code. Ingeneral, the transferred nucleic acid is incorporated into the plant'sgerm line. Transgene can also describe any DNA sequence, regardless ofwhether it contains a gene coding sequence or it has been artificiallyconstructed, which has been introduced into a plant or vector constructin which it was previously not found.

New Soybean Resistant to Three Root-Knot Nematodes, Race 3 of SoybeanCyst Nematode, and Stem Canker

The present disclosure relates to a new soybean variety, ‘G03-1187RR’.This new variety is a late Maturing Group (MG) VII (Relative Maturityabout 7.9), glyphosate tolerant, and resistant to many pests that affectsoybeans, including southern, peanut and Javanese root-knot nematodes,race 3 of soybean cyst nematode, and stem canker. ‘G03-1187RR’ also hasimproved seed yield when compared to existing late MG VII Roundup® Readycultivars. Thus, the new variety is adapted to areas of the (such as thesouthern USA) that commonly grow MG VII soybean cultivars and to areasthat are known to have or expected to have damaging levels of thesouthern, peanut, and Javanese root-knot nematodes, race 3 of soybeancyst nematode, and/or stem canker.

Thus provided herein is a seed of soybean variety ‘G03-1187RR’, whereinrepresentative sample seed of the variety is deposited under (ATCCAccession No. PTA-12952). Also provided is bulk soybean seed containingsuch seeds. The disclosure provides soybean plants having or consistingof the morphological and physiological characteristics of ‘G03-1187RR’.The disclosure also provides soybean plants having one or more of themorphological and physiological characteristics of ‘G03-1187RR (such asthose listed in Tables 2-10). In one example, such plans have or includethe characteristics noted in Tables 2-10, for example resistance tosouthern, peanut and Javanese root-knot nematodes, race 3 of soybeancyst nematode, and to stem canker. Also provided are seeds of suchplants, progeny of such plants, parts of such plants (such as pollen,ovules and cells). In one example, the disclosure provides soybeanplants having the genotype of ‘G03-1187RR’. For example, the disclosureprovides plants produced by growing the seed of the new soybean variety‘G03-1187RR’.

The disclosed ‘G03-1187RR’ plants, and in some examples progeny thereof,have increased seed yield as compared to other a late Maturity Group VIIsoybeans, such as USG 7732nRR. For example, the disclosed ‘G03-1187RR’plants, and in some examples progeny thereof, have a seed yield of atleast 50 bu/a. In some examples, the disclosed ‘G03-1187RR’ plants, andin some examples progeny thereof, have a seed yield that is at least 5%,at least 6%, at least 7%, at least 8%, at least 9%, or at least 10%greater than another late Maturity Group VII soybean, such as USG7732nRR. For example, the disclosed ‘G03-1187RR’ plants, and in someexamples progeny thereof, have disease rating for resistance to southernroot-knot nematode of no more than 2.5, no more than 2.4, or no morethan 2.3 (such as 2 to 2.5, 2.1 to 2.5, 2.2 to 2.5, or 2.3 to 2.5), havedisease rating for resistance to peanut root-knot nematode of no morethan 2.5, no more than 2.4, or no more than 2 (such as 1 to 2.5), havedisease rating for resistance to Javanese root-knot nematode of no morethan 2.5, no more than 2, or no more than 1.5 (such as 1 to 2.5), areresistant to race 3 of soybean cyst nematode, have disease rating forresistance to stem canker of no more than 2, no more than 1.5, or nomore than 1 (such as 0 to 2), or combinations thereof.

The disclosed ‘G03-1187RR’ plants and seeds can be used to produce othersoybean plants and seeds, for example as part of a breeding program.Choice of breeding or selection methods using to generate new soybeanplants and seeds can depend on the mode of plant reproduction, theheritability of the trait(s) being improved, and the type of varietyused commercially (e.g., F₁ hybrid variety, pureline variety, etc.). Forhighly heritable traits, a choice of superior individual plantsevaluated at a single location can be effective, whereas for traits withlow heritability, selection can be based on mean values obtained fromreplicated evaluations of families of related plants. Popular selectionmethods commonly include pedigree selection, modified pedigreeselection, mass selection, recurrent selection and backcrossing.

The complexity of inheritance influences choice of the breeding method.Backcross breeding can be used to transfer one or a few favorable genesfor a highly heritable trait into a desirable variety. This approach hasbeen used extensively for breeding disease-resistant varieties (e.g.,see Bowers et al., 1992. Crop Sci. 32(1):67-72; Nickell and Bernard,1992. Crop Sci. 32(3):835). Various recurrent selection techniques canbe used to improve quantitatively inherited traits controlled bynumerous genes.

Promising advanced breeding lines can be thoroughly tested and comparedto appropriate standards in environments representative of thecommercial target area(s) for generally three or more years. The best ormost preferred lines are candidates for new commercial varieties. Thosestill deficient in a few traits may be used as parents to produce newpopulations for further selection.

A difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valuecan be masked by other confounding plant traits or environmentalfactors. One method of identifying a superior plant is to observe itsperformance relative to other experimental plants and to one or morewidely grown standard varieties. Single observations can be generallyinconclusive, while replicated observations provide a better estimate ofgenetic worth.

Plant breeding can result in new, unique and superior soybean varietiesand hybrids from ‘G03-1187RR’. Two or more parental lines can beselected (such as ‘G03-1187RR’ as one of the lines), followed byrepeated selfing and selection, producing many new genetic combinations.Each year, the germplasm to advance to the next generation is selected.This germplasm is grown under unique and different geographical,climatic and soil conditions, and further selections are then made,during and at the end of the growing season. The varieties developed canbe unpredictable, because the selection occurs in unique environments,with no control at the DNA level (using conventional breedingprocedures), and with millions of different possible geneticcombinations being generated.

The development of new soybean varieties from ‘G03-1187RR’ involves thedevelopment and selection of soybean varieties, the crossing of thesevarieties and selection of progeny from the superior hybrid crosses. Ahybrid seed is produced by manual crosses between selected male-fertileparents or by using male sterility systems. Hybrids can be identified byusing certain single locus traits such as pod color, flower color,pubescence color or herbicide resistance which indicate that the seed istruly a hybrid. Additional data on parental lines as well as thephenotype of the hybrid can influence a decision whether to continuewith the specific hybrid cross.

Pedigree breeding and recurrent selection breeding methods can be usedto develop varieties from breeding populations. Breeding programscombine desirable traits from two or more varieties or variousbroad-based sources into breeding pools from which varieties aredeveloped by selfing and selection of desired phenotypes. Pedigreebreeding is commonly used for the improvement of self-pollinating crops.Two parents (e.g., wherein one of the parents is ‘G03-1187RR’) whichpossess favorable, complementary traits are crossed to produce an F₁. AnF2 population is produced by selfing one or several F₁'s. Selection ofthe best or most preferred individuals can begin in the F₂ population(or later depending upon the breeding objectives); then, beginning inthe F₃, the best or most preferred individuals in the best families canbe selected. Replicated testing of families can begin in the F₃ or F₄generation to improve the effectiveness of selection for traits with lowheritability. At an advanced stage of inbreeding (i.e., F₆ and F₇), thebest lines or mixtures of phenotypically similar lines can be tested forpotential commercial release as new varieties.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified or createdby intercrossing several different parents. The best or most preferredplants are selected based on individual superiority, outstandingprogeny, or excellent combining ability. The selected plants areintercrossed to produce a new population in which further cycles ofselection are continued.

Backcross breeding has been used to transfer genetic loci for simplyinherited, highly heritable traits into a desirable homozygous varietywhich is the recurrent parent (e.g., ‘G03-1187RR’). The source of thetrait to be transferred is called the donor or nonrecurrent parent. Theresulting plant is typically expected to have the attributes of therecurrent parent (e.g., variety) and the desirable trait transferredfrom the donor parent. After the initial cross, individuals possessingthe phenotype of the donor parent are selected and repeatedly crossed(backcrossed) to the recurrent parent. The resulting plant is typicallyexpected to have the attributes of the recurrent parent (e.g., variety)and the desirable trait transferred from the donor parent.

The single-seed descent procedure can refer to planting a segregatingpopulation, harvesting a sample of one seed per plant, and using theone-seed sample to plant the next generation. When the population hasbeen advanced from the F₂ to the desired level of inbreeding, the plantsfrom which lines are derived will each trace to different F₂individuals. The number of plants in a population declines eachgeneration due to failure of some seeds to germinate or some plants toproduce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population are represented by a progeny whengeneration advance is completed.

In a multiple-seed procedure, one or more pods from each plant in apopulation are commonly harvested and threshed together to form a bulk.Part of the bulk is used to plant the next generation and part is put inreserve. The procedure has been referred to as modified single-seeddescent or the pod-bulk technique. The multiple-seed procedure has beenused to save labor at harvest. It is considerably faster to thresh podswith a machine than to remove one seed from each by hand for thesingle-seed procedure. The multiple-seed procedure also makes itpossible to plant the same number of seeds of a population eachgeneration of inbreeding. Sufficient numbers of seeds are harvested tomake up for those plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard. 1960. Principles of plant breeding.

Breeding Soybean Variety ‘G03-1187RR’

Methods for crossing the new soybean variety ‘G03-1187RR’ with itself ora second plant are provided, as are the seeds and plants produced bysuch methods. Such methods can be used for propagation of the newsoybean variety ‘G03-1187RR’, or can be used to produce hybrid soybeanseeds and the plants grown therefrom. Hybrid soybean plants can be used,for example, in the commercial production of soy products or in breedingprograms for the production of novel soybean varieties. A hybrid plantcan also be used as a recurrent parent at any given stage in abackcrossing protocol during the production of a single locus conversion(for example introduction of one or more desirable traits) of the newsoybean variety ‘G03-1187RR’.

Methods of producing soybean plants and/or seed are provided. Such amethod can include crossing the new soybean variety ‘G03-1187RR’ withitself or a second soybean plant and harvesting a resulting soybeanseed, such as an F₁ hybrid seed. The resulting plant can be grown,resulting in a soybean plant or part thereof.

In one example methods of producing an inbred soybean plant derived fromsoybean variety ‘G03-1187RR’ are provided. In one example such methodsinclude (a) preparing a progeny plant derived from soybean variety‘G03-1187RR’ by crossing a plant of the soybean variety ‘G03-1187RR’with a soybean plant of a second variety; (b) crossing the progeny plantwith itself or a second plant to produce a seed of a progeny plant of asubsequent generation; (c) growing a progeny plant of a subsequentgeneration from said seed and crossing the progeny plant of a subsequentgeneration with itself or a second plant; and (d) repeating steps (b)and (c) for an additional at least 2 generations (such as at least 3, atleast 4, at least 5, at least 6, at least 7, at least 8 at least 9, atleast 10, at least 15 or at least 20, such as 2 to 10, 3 to 10, or 3 to15 generations) with sufficient inbreeding to produce an inbred soybeanplant derived from the soybean variety ‘G03-1187RR’.

The second plant crossed with the new soybean variety ‘G03-1187RR’ forthe purpose of developing novel soybean varieties, is typically a plantwhich either themselves exhibit one or more desirable characteristics orwhich exhibit one or more desired characteristic(s) when in hybridcombination. In one example, the second soybean plant is transgenic.Exemplary desired characteristics include, but are not limited to:increased seed yield, lodging resistance, emergence, increased seedlingvigor, modified maturity date, desired plant height, high oil content,high protein content, herbicide tolerance, drought tolerance, heattolerance, low or high soil pH level tolerance, salt tolerance,resistance to an insect, resistance to a bacterial disease, resistanceto a viral disease, resistance to a fungal disease, resistance to anematode, resistance to a pest, male sterility, site-specificrecombination; abiotic stress tolerance; modified phosphoruscharacteristics; modified antioxidant characteristics; modifiedessential seed amino acid characteristics; modified fatty acidmetabolism, modified carbohydrate metabolism, and modified soybean fibercharacteristics.

When the new soybean variety ‘G03-1187RR’ is crossed with anotherdifferent variety, first generation (F₁) soybean progeny are produced.The hybrid progeny are produced regardless of characteristics of the twovarieties produced. As such, an F₁ hybrid soybean plant can be producedby crossing ‘G03-1187RR’ with any second soybean plant. The secondsoybean plant can be genetically homogeneous (e.g., inbred) or canitself be a hybrid. Therefore the disclosure provides any F₁ hybridsoybean plant produced by crossing the new soybean variety ‘G03-1187RR’with a second soybean plant (such as a transgenic plant having one ormore genes that confer to the plant one or more desiredcharacteristics).

Soybean plants (Glycine max) can be crossed by either natural ormechanical techniques (see, e.g., Fehr. 1980. “Soybean.” In:Hybridization of Crop Plants. Fehr and Hadley (eds). Madison, Wis.: Am.Soc. Agron., Crop Sci. Soc. Am., pp. 590-599). Natural pollinationoccurs in soybeans either by self pollination or natural crosspollination, which typically is aided by pollinating organisms. Ineither natural or artificial crosses, flowering and flowering time canbe a consideration. Soybean is a short-day plant, but there isconsiderable genetic variation for sensitivity to photoperiod. Thecritical day length for flowering can range from about 13 hours forgenotypes adapted to tropical latitudes to about 24 hours forphotoperiod-insensitive genotypes grown at higher latitudes. Soybeanscan be insensitive to day length for about 9 days after emergence.Photoperiods shorter than the critical day length can be needed forapproximately 7 days to approximately 26 days to complete flowerinduction.

Sensitivity to day length can be a consideration when genotypes aregrown outside of their area of adaptation. When genotypes adapted totropical latitudes are grown in the field at higher latitudes, they maynot mature before frost occurs. Plants can be induced to flower andmature earlier by creating artificially short days or by grafting (Fehr.1980. “Soybean.” In: Hybridization of Crop Plants. Fehr and Hadley(eds). Madison, Wis.: Am. Soc. Agron., Crop Sci. Soc. Am., pp. 590-599).Soybeans can be grown in winter nurseries located at sea level intropical latitudes where day lengths are shorter than their criticalphotoperiod. The short day lengths and warm temperatures encourage earlyflowering and seed maturation, and genotypes can produce a seed crop inabout 90 days or fewer after planting. Early flowering can be useful forgeneration advance when only a few self-pollinated seeds per plant aredesired, but usually not for artificial hybridization because theflowers self-pollinate before they are large enough to manipulate forhybridization. Artificial lighting can be used to extend the natural daylength to about 14.5 hours to obtain flowers suitable for hybridizationand to increase yields of self-pollinated seed. The effect of a shortphotoperiod on flowering and seed yield can be partly offset byaltitude. At tropical latitudes, varieties adapted to the northern U.S.perform more like those adapted to the southern U.S. at high altitudesthan they do at sea level. The light level for delay of flowering can bedependent on the quality of light emitted from the source and thegenotype being grown. For example, blue light with a wavelength of about480 nm typically needs more than about 30 times the energy to inhibitflowering as red light with a wavelength of about 640 nm (Parker et al.1946. Bot. Gaz. 108:1-26).

Temperature can also affect the flowering and development of soybean. Itcan influence the time of flowering and suitability of flowers forhybridization. Temperatures below about 21° C. or above about 32° C. canreduce floral initiation or seed set (Hammer. 1969. “Glycine max (L.)Merrill.” In: The Induction of Flowering: Some Case Histories. Evans(ed). Ithaca, N.Y.: Cornell University Press, pp. 62-89; van Schaik andProbst. 1978. Agron. J. 50:192-197). Artificial hybridization istypically successful between about 26° C. and about 32° C. becausecooler temperatures can reduce pollen shed and result in flowers thatself-pollinate before they are large enough to manipulate. Warmertemperatures can be associated with increased flower abortion caused bymoisture stress; however, successful crosses can be achieved up to about35° C. if soil moisture is adequate.

Soybeans are classified as indeterminate, semi-determinate, anddeterminate based on the abruptness of stem termination after floweringbegins. When grown at their latitude of adaptation, indeterminategenotypes flower when about one-half of the nodes on the main stem havedeveloped. They have short racemes with few flowers, and their terminalnode has only a few flowers. Semi-determinate genotypes also flower whenabout one-half of the nodes on the main stem have developed, but nodedevelopment and flowering on the main stem stops more abruptly than onindeterminates. Their racemes are short and have few flowers, except forthe terminal one, which may have several times more flowers than thoselower on the plant. Determinate varieties begin flowering when all ormost of the nodes on the main stem have developed. They usually haveelongated racemes that may be several centimeters in length and may havea large number of flowers.

Soybean flowers typically are self-pollinated on the day the corollaopens. The amount of natural crossing, which is typically associatedwith insect vectors such as honeybees, is approximately 1% for adjacentplants within a row and approximately 0.5% between plants in adjacentrows. The structure of soybean flowers is similar to that of otherlegume species and consists of a calyx with approximately five sepals, acorolla with approximately five petals, approximately ten stamens, and apistil. The stigma is receptive to pollen about 1 day before anthesisand remains receptive for approximately 2 days after anthesis, if theflower petals are not removed. The anthers dehisce on the day ofanthesis, pollen grains fall on the stigma, and within approximately 10hours, the pollen tubes reach the ovary and fertilization is completed.

Self-pollination can occur naturally in soybean with no manipulation ofthe flowers. In some examples, the crossing of two soybean plants isaccomplished using artificial hybridization. In artificialhybridization, the flower used as a female in a cross is manually crosspollinated prior to maturation of pollen from the flower, therebypreventing self fertilization, or alternatively, the male parts of theflower are emasculated using known methods. Exemplary methods foremasculating the male parts of a soybean flower include physical removalof the male parts, use of a cytoplasmic or genetic factor conferringmale sterility, and application of a chemical gametocide to the maleparts.

For artificial hybridization employing emasculation, flowers that areexpected to open the following day are selected on the female parent.The buds are swollen and the corolla is just visible through the calyxor has begun to emerge. Usually no more than two buds on a parent plantare prepared, and all self-pollinated flowers or immature buds areremoved, for example with forceps. Immature buds, such as those hiddenunder the stipules at the leaf axil, are removed. The calyx is removed,for example by grasping a sepal with the forceps, pulling it down andaround the flower, and repeating the procedure until the five sepals areremoved. The exposed corolla is removed, for example by grasping it justabove the calyx scar, then lifting and wiggling the forcepssimultaneously. The ring of anthers is visible after the corolla isremoved, unless the anthers were removed with the petals.Cross-pollination can then be performed using, for example, petri dishesor envelopes in which male flowers have been collected. Desiccatorscontaining calcium chloride crystals are used in some environments todry male flowers to obtain adequate pollen shed.

Emasculation is not necessary to prevent self-pollination (Walker et al.1979. Crop Sci. 19:285-286). When emasculation is not used, the anthersnear the stigma can be removed to make the stigma visible forpollination. The female flower is usually hand-pollinated immediatelyafter it is prepared; although a delay of several hours does not reduceseed set. Pollen shed typically begins in the morning and can end whentemperatures are above about 30° C. Pollen shed can also begin later andcontinue throughout much of the day with more moderate temperatures.

Pollen is available from a flower with a recently opened corolla, butthe degree of corolla opening associated with pollen shed can varyduring the day. In many environments, collection and use of male flowersimmediately without storage can be conducted. In the southern U.S. andother humid climates, pollen shed occurs in the morning when femaleflowers are more immature and difficult to manipulate than in theafternoon, and the flowers can be damp from heavy dew. In thosecircumstances, male flowers are collected into envelopes or petri dishesin the morning, and the open container is typically placed in adesiccator for about 4 hours at a temperature of about 25° C. Thedesiccator can be taken to the field in the afternoon and kept in theshade to prevent excessive temperatures from developing within it.Pollen viability can be maintained in flowers for up to about 2 dayswhen stored at about 5° C. In a desiccator at about 3° C., flowers canbe stored successfully for several weeks; however, varieties can differin the percentage of pollen that germinates after long-term storage.

Either with or without emasculation of the female flower, handpollination can be carried out by removing the stamens and pistil from aflower of the male parent and gently brushing the anthers against thestigma of the female flower. Access to the stamens can be achieved byremoving the front sepal and keel petals, or piercing the keel withclosed forceps and allowing them to open to push the petals away.Brushing the anthers on the stigma causes them to rupture, and highpercentages of successful crosses are typically obtained when pollen isclearly visible on the stigma. Pollen shed can be checked by tapping theanthers before brushing the stigma. Several male flowers can be used toobtain suitable pollen shed when conditions are unfavorable, or the samemale can be used to pollinate several flowers with good pollen shed.

When male flowers are not collected and dried in a desiccator, theparents of a cross can be planted adjacent to each other. Plants aretypically grown in rows about 65 cm to about 100 cm apart. Yield ofself-pollinated seed from an individual plant can range from a few seedsto more than about 1,000 as a function of plant density. A density ofabout 30 plants/m of row can be used when about 30 or fewer seeds perplant is adequate, about 10 plants/m can be used to obtain about 100seeds/plant, and about 3 plants/m usually results in a high seedproduction per plant. Densities of about 12 plants/m or less arecommonly used for artificial hybridization.

Multiple planting dates about 7 days to about 14 days apart cantypically be used to match parents of different flowering dates. Whendifferences in flowering dates are extreme between parents, flowering ofthe later parent can be hastened by creating an artificially short day.Alternatively, flowering of the earlier parent can be delayed by use ofartificially long days or delayed planting. For example, crosses withgenotypes adapted to the southern U.S. are made in northern U.S.locations by covering the late genotype with a box, large can, orsimilar container to create an artificially short photoperiod of about12 hours for about 15 days beginning when there are three nodes withtrifoliate leaves on the main stem. Plants induced to flower early tendto have flowers that self-pollinate when they are small and can bedifficult to prepare for hybridization.

Grafting can be used to hasten the flowering of late floweringgenotypes. A scion from a late genotype grafted on a stock that hasbegun to flower can begin to bloom up to about 42 days earlier thannormal. First flowers on the scion can appear from about 21 days toabout 50 days after the graft.

Observing pod development approximately 7 days after pollination isgenerally sufficient to identify a successful cross. Abortion of podsand seeds can occur several weeks after pollination, but the percentageof abortion is typically low if plant stress is minimized. Pods thatdevelop from artificial hybridization can be distinguished fromself-pollinated pods by the presence of the calyx scar, caused byremoval of the sepals. The sepals typically begin to fall off as thepods mature; therefore, harvest can be completed at or immediatelybefore the time the pods reach their mature color. Harvesting pods earlyalso avoids any loss by shattering.

Once harvested, pods are typically air-dried at not more than about 38°C. until the seeds contain approximately 13% moisture or less. The seedsare then removed. Seed can be stored at about 25° C. for up to a year ifrelative humidity is approximately 50% or less. In humid climates,germination percentage declines rapidly unless the seed is dried toabout 7% moisture and stored in an air-tight container at roomtemperature. Long-term storage in any climate can be accomplished bydrying seed to about 7% moisture and storing it at about 10° C. or lessin a room maintained at about 50% relative humidity or in an air-tightcontainer.

Soybean Plants Having One or More Desired Heritable Traits

The disclosure provides plants of the new soybean variety ‘G03-1187RR’modified to include one or more desired heritable traits. In someexamples, such plants can be developed using backcrossing or geneticengineering (for example by introducing one or more transgenes into the‘G03-1187RR’ variety, wherein the transgenes encode one or more desiredtraits), wherein essentially all of the desired morphological andphysiological characteristics of the ‘G03-1187RR’ variety are recovered(such as resistance to southern, peanut and Javanese root-knotnematodes, race 3 of soybean cyst nematode, and stem canker, andincreased seed yield) in addition to a genetic locus transferred intothe plant via the backcrossing technique. Plants developed using suchmethods can be referred to as a single locus converted plant.

In one example, the method of introducing one or more desired traitsinto soybean variety ‘G03-1187RR’ includes (a) crossing a plant ofvariety ‘G03-1187RR’ with a second plant having one or more desiredtraits to produce F₁ progeny plants; (b) selecting F₁ progeny plantsthat have the one or more desired traits to produce selected F₁ progenyplants; (c) crossing the selected progeny plants with at least a firstplant of variety ‘G03-1187RR’ to produce backcross progeny plants; (d)selecting backcross progeny plants that have the one or more desiredtraits and physiological and morphological characteristics of soybeanvariety ‘G03-1187RR’ to produce selected backcross progeny plants; and(e) repeating steps (c) and (d) one or more times in succession toproduce selected second or higher backcross progeny plants that have theone or more desired traits and the physiological and morphologicalcharacteristics of soybean variety ‘G03-1187RR’ when grown in the sameenvironmental conditions.

Backcrossing methods can be used to improve or introduce acharacteristic into the new soybean variety ‘G03-1187RR’ (for exampleusing the methods provided in U.S. Pat. No. 6,140,556). The parentalsoybean plant which contributes the locus for the desired characteristicis termed the “nonrecurrent” or “donor” parent. This terminology refersto the fact that the nonrecurrent parent is used one time in thebackcross protocol and therefore does not recur. The parental soybeanplant to which the locus or loci from the nonrecurrent parent aretransferred is known as the recurrent parent as it is used for severalrounds in the backcrossing protocol (Poehlman and Sleper. 1995.“Breeding Field Crops” Ames, Iowa: Iowa State University Press; Fehr.1987. “Principles of variety development.” In Theory and Technique(Vol. 1) and Crop Species Soybean (Vol. 2). New York: MacmillanPublishing Company, pp. 360-376; Sprague and Dudley, eds. 1988. Corn andImprovement, 3rd edition). In a typical backcross protocol, the originalvariety of interest (recurrent parent, e.g., ‘G03-1187RR’) is crossed toa second variety (nonrecurrent parent) that carries the single locus ofinterest (such as a desirable trait) to be transferred. The resultingprogeny from this cross are then crossed again to the recurrent parentand the process is repeated until a soybean plant is obtained whereinessentially all of the desired morphological and physiologicalcharacteristics of the recurrent parent (e.g., ‘G03-1187RR’) arerecovered (such as resistance to southern, peanut and Javanese root-knotnematodes, race 3 of soybean cyst nematode, and stem canker, andincreased seed yield) in the converted plant, in addition to the singletransferred locus from the nonrecurrent parent.

The goal of a backcross protocol is to alter or substitute a singletrait or characteristic in the original variety, such as ‘G03-1187RR’.To accomplish this, a single locus of the recurrent variety is modifiedor substituted with the desired locus from the nonrecurrent parent,while retaining essentially all of the rest of the desired genetic, andtherefore the desired physiological and morphological constitution ofthe original variety. The choice of the particular nonrecurrent parentcan depend on the purpose of the backcross; for example, a major purposeis to add a commercially desirable, agronomically important trait to theplant. The exact backcrossing protocol can depend on the characteristicor trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the characteristicbeing transferred is a dominant allele, a recessive allele can also betransferred. In this instance, it can be useful to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

In a backcross where the desired characteristic being transferred to therecurrent parent is controlled by a major gene which can be readilyevaluated during the backcrossing, it is common to conduct enoughbackcrosses to avoid testing individual progeny for specific traits suchas yield in extensive replicated tests. In general, four or morebackcrosses are used when there is no evaluation of the progeny forspecific traits, such as yield. As in this example, lines with thephenotype of the recurrent parent can be composited without the usualreplicated tests for traits such as yield, protein or oil percentage inthe individual lines.

Soybean varieties can also be developed from more than two parents, forexample using modified backcrossing, which uses different recurrentparents during the backcrossing. Modified backcrossing can be used toreplace the original recurrent parent with a variety having certain moredesirable characteristics, or multiple parents can be used to obtaindifferent desirable characteristics from each.

Many single locus traits are known that are not regularly selected forin the development of a new inbred but that can be improved bybackcrossing techniques. Single locus traits can be, but are notnecessarily, transgenic. Examples of these traits include, but are notlimited to, male sterility, herbicide resistance, abiotic stresstolerance (such as tolerance or resistance to drought, heat, cold, lowor high soil pH level, and/or salt), resistance to bacterial, fungal, orviral disease, insect resistance, restoration of male fertility,enhanced nutritional quality, modified phosphorus characteristics,modified antioxidant characteristics, modified essential seed amino acidcharacteristics, modified fatty acid metabolism, modified carbohydratemetabolism, and modified soybean fiber characteristics, yield stability,and yield enhancement. These comprise genes generally inherited throughthe nucleus. Thus plants of soybean variety ‘G03-1187RR’ that include asingle locus conversion (such as one that confers a desired trait) areprovided herein.

Direct selection can be applied where the single locus acts as adominant trait.

An example of a dominant trait is the herbicide resistance trait (suchas glyphosate resistance). For the selection process, the progeny of theinitial cross are sprayed with a herbicide (such as RoundUp®) prior tothe backcrossing. The spraying eliminates any plants which do not havethe desired herbicide resistance characteristic; only those plants whichhave the herbicide resistance gene are used in the subsequent backcross.This process is then repeated for all additional backcross generations.

Selection of soybean plants for breeding may not be dependent on thephenotype of a plant and instead can be based on genetic investigations.For example, a suitable genetic marker can be used which is closelygenetically linked to a desired trait. One of these markers cantherefore be used to identify the presence or absence of a trait in theoffspring of a particular cross, and hence can be used in selection ofprogeny for continued breeding. This technique is referred to as markerassisted selection. Any other type of genetic marker or other assaywhich is able to identify the relative presence or absence of a trait ofinterest in a plant can also be useful for breeding. Procedures formarker assisted selection applicable to the breeding of soybeans arewell known in the art. Such methods can be useful in the case ofrecessive traits and variable phenotypes, or where conventional assaysare more expensive, time consuming or otherwise disadvantageous. Typesof genetic markers which can be used, but are not limited to, SimpleSequence Length Polymorphisms (SSLPs), Randomly Amplified PolymorphicDNAs (RAPDs), DNA Amplification Fingerprinting (DAF), SequenceCharacterized Amplified Regions (SCARs), Arbitrary Primed PolymeraseChain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs)(EP 534 858, which is incorporated herein by reference in its entirety),and Single Nucleotide Polymorphisms (SNPs).

Qualitative characters can be useful as phenotype-based genetic markersin soybeans; however, some or many may not differ among varietiescommonly used as parents (Bernard and Weiss. 1973. supra). Widely usedgenetic markers include flower color (purple dominant to white),pubescence color (brown dominant to gray), and pod color (brown dominantto tan). The association of purple hypocotyl color with purple flowersand green hypocotyl color with white flowers is commonly used toidentify hybrids in the seedling stage. Differences in maturity, height,hilum color, and pest resistance between parents can also be used toverify hybrid plants.

Useful or desirable traits can be introduced by backcrossing, as well asdirectly into a plant by genetic transformation methods. Genetictransformation can therefore be used to insert a selected transgene intothe ‘G03-1187RR’ variety or can, alternatively, be used for thepreparation of transgenes which can be introduced by backcrossing. Thus,the disclosure provides methods of producing a plant of soybean variety‘G03-1187RR’ that includes one or more added desired traits, for examplethat include introducing a transgene(s) conferring the one or moredesired traits into a plant of soybean variety ‘G03-1187RR (for exampleby transformation with a transgene that confers upon the soybean plantthe desired trait), thereby producing a plant of soybean variety‘G03-1187RR’ that includes the one or more added desired traits.

Methods for the transformation of many economically important plants,including soybeans, are well known. Methods for introducing a desirednucleic acid molecule (e.g., transgene), such as DNA, RNA, or inhibitoryRNAs, are well known in the art, and the disclosure is not limited toparticular methods. Exemplary techniques which can be employed for thegenetic transformation of soybeans include, but are not limited to,electroporation, microprojectile bombardment, Agrobacterium-mediatedtransformation and direct DNA uptake by protoplasts.

To effect transformation by electroporation, friable tissues, such as asuspension culture of cells or embryogenic callus, can be used.Alternatively, immature embryos or other organized tissue can betransformed directly. In this technique, the cell walls of target cellscan be partially degraded by exposing them to pectin-degrading enzymes(pectolyases) or mechanically wound tissues in a controlled manner.

Protoplasts can also be employed for electroporation transformation ofplants (Bates. 1994. Mol. Biotechnol. 2(2):135-145; Lazzeri. 1995.Methods Mol. Biol. 49:95-106). For example, the generation of transgenicsoybean plants by electroporation of cotyledon-derived protoplasts hasbeen described by Dhir and Widholm (WO 1992/017598).

In microprojectile bombardment, particles (such as those comprised oftungsten, platinum, or gold) are coated with nucleic acids and deliveredinto cells by a propelling force. For the bombardment, cells insuspension are concentrated on filters or solid culture medium.Alternatively, immature embryos or other target cells can be arranged onsolid culture medium. The cells to be bombarded are positioned at anappropriate distance below the macroprojectile stopping plate. Anexemplary method for delivering DNA into plant cells by acceleration isthe Biolistics Particle Delivery System, which can be used to propelparticles coated with DNA or cells through a screen, such as a stainlesssteel or Nytex screen, onto a surface covered with target soybean cells.The screen disperses the particles so that they are not delivered to therecipient cells in large aggregates. A screen intervening between theprojectile apparatus and the cells to be bombarded can reduce the sizeof projectiles aggregate and contribute to a higher frequency oftransformation by reducing the damage inflicted on the recipient cellsby projectiles that are too large. Microprojectile bombardment methodscan be used to transform soybeans, as described, for example, in U.S.Pat. No. 5,322,783.

Agrobacterium-mediated transfer is a well-known method in the art forintroducing gene loci into plant cells. DNA can be introduced into wholeplant tissues, thereby bypassing the need for regeneration of an intactplant from a protoplast. Agrobacterium transformation vectors arecapable of replication in E. coli as well as Agrobacterium, allowing forconvenient manipulations (Klee et al. 1985. Bio. Tech. 3(7):637-342).Moreover, vectors for Agrobacterium-mediated gene transfer have improvedthe arrangement of genes and restriction sites in the vectors tofacilitate the construction of vectors capable of expressing variouspolypeptide coding genes. Such vectors have convenient multi-linkerregions flanked by a promoter and a polyadenylation site for directexpression of inserted polypeptide coding genes. Additionally,Agrobacterium containing both armed and disarmed Ti genes can be usedfor transformation. The use of Agrobacterium-mediated plant integratingvectors to introduce DNA into plant cells is well known (e.g., Fraley etal. 1985. Bio. Tech. 3(7):629-635; U.S. Pat. No. 5,563,055), and its usefor soybean transformation has been described (Chee and Slightom. 1995.Methods Mol. Biol. 44:101-119; U.S. Pat. No. 5,569,834). Briefly, planttissue (often leaves) is cut into small pieces, e.g. 10 mm×10 mm, andsoaked for 10 minutes in a fluid containing suspended Agrobacterium.Some cells along the cut will be transformed by the bacterium, whichinserts its DNA into the cell, which is placed on selectable rooting andshooting media, allowing the plants to regrow. Some plants can betransformed just by dipping the flowers into suspension of Agrobacteriumand then planting the seeds in a selective medium.

Transformation of plant protoplasts can also be achieved using methodsbased on calcium phosphate precipitation, polyethylene glycol treatment,electroporation, and combinations of these treatments (e.g., Potrykus etal. 1985. Mol. Gen. Genet. 199(2):169-177; Omirulleh et al. 1993. PlantMol. Biol. 21(3):415-428; Fromm et al. 1986. Nature. 319(6056):791-739;Uchimiya et al. 1986. Mol. Gen. Genet. 204(2):207-207; Marcotte et al.1988. Nature 335(6189):454-457). The ability to regenerate soybeanplants from protoplasts makes these techniques applicable to soybean(Dhir et al. 1991. Plant Cell Rep. 10(2):97-101).

In one example, such methods can also be used to introduce transgenesfor the production of proteins in transgenic soybeans. The resultingproduced protein can be harvested from the transgenic soybean. Thetransgene can be harvested from the transgenic plants that areoriginated or are descended from the new soybean variety ‘G03-1187RR’, aseed of ‘G03-1187RR’ or a hybrid progeny of ‘G03-1187RR’.

Numerous different genes are known and can be introduced into a soybeanplant ‘G03-1187RR’ or progeny thereof. Non-limiting examples ofparticular genes and corresponding phenotypes that can be chosen forintroduction into a soybean plant are provided herein.

Herbicide Resistance

Numerous herbicide resistance genes are known and can be used with themethods and plants provided herein. In particular examples, a herbicideresistance gene confers tolerance to an herbicide comprising glyphosate,sulfonylurea, imidazalinone, dicamba, glufosinate, phenoxy proprionicacid, cyclohexone, triazine, benzonitrile, broxynil, L-phosphinothricin,cyclohexanedione, chlorophenoxy acetic acid, or combinations thereof.

In one example the herbicide resistance gene is a gene that confersresistance to a herbicide that inhibits the growing point or meristem,such as an imidazalinone or a sulfonylurea. Exemplary genes in thiscategory code for mutant ALS and AHAS enzyme as described, for example,by Lee et al. (1988. Embryo J. 7:1241-8) and Miki et al. (1990. Theoret.Appl. Genet. 80:449-458).

Resistance genes for glyphosate (resistance conferred by mutant5-enolpyruvl-3 phosphikimate synthase (EPSP) and aroA genes,respectively) and other phosphono compounds such as glufosinate(phosphinothricin acetyl transferase (PAT) and Streptomyceshygroscopicus phosphinothricin-acetyl transferase (bar) genes) can beused (e.g., see U.S. Pat. No. 4,940,835). Examples of specific EPSPStransformation events conferring glyphosate resistance are described,for example, in U.S. Pat. No. 6,040,497.

DNA molecules encoding a mutant aroA gene are known (e.g., ATCCaccession number 39256 and U.S. Pat. No. 4,769,061), as are sequencesfor glutamine synthetase genes, which confer resistance to herbicidessuch as L-phosphinothricin (e.g., U.S. Pat. No. 4,975,374),phosphinothricin-acetyltransferase (e.g., U.S. Pat. No. 5,879,903).DeGreef et al. (1989. Bio/Technology 61-64) describe the production oftransgenic plants that express chimeric bar genes coding forphosphinothricin acetyl transferase activity. Exemplary genes conferringresistance to phenoxy propionic acids and cyclohexones, such assethoxydim and haloxyfop are the Acct-S1, Accl-S2 and Acct-S3 genesdescribed by Marshall et al. (1992. Theor Appl Genet. 83:435-442).

Genes conferring resistance to a herbicide that inhibits photosynthesisare also known, such as, a triazine (psbA and gs+genes) and abenzonitrile (nitrilase gene) (see Przibilla et al., 1991. Plant Cell.3:169-174). Nucleotide sequences for nitrilase genes are disclosed inU.S. Pat. No. 4,810,648, and DNA molecules containing these genes areavailable under ATCC Accession Nos. 53435, 67441, and 67442. Cloning andexpression of DNA coding for a glutathione S-transferase is described byHayes et al. (1992. Biochem. J. 285:173).

U.S. Patent Publication No: 20030135879 describes dicamba monooxygenase(DMO) from Pseuodmonas maltophilia, which is involved in the conversionof a herbicidal form of the herbicide dicamba to a non-toxic3,6-dichlorosalicylic acid and thus can be used for producing plantstolerant to this herbicide.

The metabolism of chlorophenoxyacetic acids, such as, for example 2,4-Dherbicide, is well known. Genes or plasmids that contribute to themetabolism of such compounds are described, for example, by Muller etal. (2006. Appl. Environ. Microbiol. 72(7):4853-4861), Don and Pemberton(1981. J Bacteriol 145(2):681-686), Don et al. (1985. J Bacteriol161(1):85-90) and Evans et al. (1971. Biochem J 122(4):543-551).

Disease Resistance

Plant defenses are often activated by specific interaction between theproduct of a disease resistance gene (R) in the plant and the product ofa corresponding avirulence (Avr) gene in the pathogen. A plant, such as‘G03-1187RR’ or progeny thereof, can be transformed with clonedresistance gene to engineer plants that are resistant to specificpathogen strains. See, for example Jones et al. (1994. Science 266:789)(tomato Cf-9 gene for resistance to Cladosporium falvum); Martin et al.(1993. Science 262(5138):1432-1436) (tomato Pto gene for resistance toPseudomonas syringae pv.); and Mindrinos et al. (1994. Cell78:1089-1099) (Arabidopsis RSP2 gene for resistance to Pseudomonassyringae).

A viral-invasive protein or a complex toxin derived therefrom can alsobe used for viral disease resistance. For example, the accumulation ofviral coat proteins in transformed plant cells imparts resistance toviral infection and/or disease development effected by the virus fromwhich the coat protein gene is derived, as well as by related viruses.See Beachy et al. (1990. Annu Rev Phytopathol 28:451-474). Coatprotein-mediated resistance has been conferred upon transformed plantsagainst alfalfa mosaic virus, cucumber mosaic virus, tobacco streakvirus, potato virus X, potato virus Y, tobacco etch virus, tobaccorattle virus and tobacco mosaic virus. Id.

A virus-specific antibody can also be used. See, for example,Tavladoraki et al. (1993. Nature 366:469-472), which shows thattransgenic plants expressing recombinant antibody genes are protectedfrom virus attack.

Logemann et al. (1992. Bio/Technology 10:305-308) disclose transgenicplants expressing a barley ribosome-inactivating gene have an increasedresistance to fungal disease.

Insect Resistance

One example of an insect resistance gene includes a Bacillusthuringiensis (Bt) protein, a derivative thereof or a syntheticpolypeptide modeled thereon (e.g., see Geiser et al., 1986. Gene 48:109,discloses a Bt Δendotoxin gene). Moreover, DNA molecules encodingΔ-endotoxin genes can be purchased from the ATCC (Manassas, Va.), forexample under ATCC Accession Nos. 40098, 67136, 31995 and 31998. Anotherexample is a lectin. See, for example, Van Damme et al. (1994. Plant MolBiol 24(5):825-830), which discloses several Clivia miniatamannose-binding lectin genes. A vitamin-binding protein can also beused, such as avidin. See WIPO Publication No. WO 1994/000992, whichteaches the use of avidin and avidin homologues as larvicides againstinsect pests.

In one example the insect resistance gene is an enzyme inhibitor, forexample, a protease, proteinase inhibitor, or an α-amylase inhibitor.See, for example, Abe et al. (1987. J. Biol. Chem. 262:16793-7;discloses a rice cysteine proteinase inhibitor), Genbank Accession Nos.Z99173.1 and DQ009797.1 which disclose proteinase inhibitor codingsequences, and Sumitani et al. (1993. Plant Mol. Biol. 21:985; disclosesStreptomyces nitrosporeus α-amylase inhibitor). An insect-specifichormone or pheromone can also be used. See, for example, Hammock et al.(1990. Nature 344:458-461; discloses juvenile hormone esterase, aninactivator of juvenile hormone).

Still other examples include an insect-specific antibody or animmunotoxin derived therefrom and a developmental-arrestive protein. SeeTaylor et al. (1994. Seventh Intl. Symposium on Molecular Plant-MicrobeInteractions (Edinburgh Scotland), Abstract #497), who describedenzymatic inactivation in transgenic tobacco via production ofsingle-chain antibody fragments.

Male Sterility

Genetic male sterility is available in soybeans and can increase theefficiency with which hybrids are made, in that it can eliminate theneed to physically emasculate the soybean plant used as a female in agiven cross (Brim and Stuber. 1973. Crop Sci. 13:528-530).Herbicide-inducible male sterility systems are known (e.g., U.S. Pat.No. 6,762,344).

Where use of male-sterility systems is desired, it can be beneficial toalso utilize one or more male-fertility restorer genes. For example,where cytoplasmic male sterility (CMS) is used, hybrid seed productioninvolves three inbred lines: (1) a cytoplasmically male-sterile linehaving a CMS cytoplasm; (2) a fertile inbred with normal cytoplasm,which is isogenic with the CMS line for nuclear genes (“maintainerline”); and (3) a distinct, fertile inbred with normal cytoplasm,carrying a fertility restoring gene (“restorer” line). The CMS line ispropagated by pollination with the maintainer line, with all of theprogeny being male sterile, as the CMS cytoplasm is derived from thefemale parent. These male sterile plants can then be efficientlyemployed as the female parent in hybrid crosses with the restorer line,without the need for physical emasculation of the male reproductiveparts of the female parent.

The presence of a male-fertility restorer gene results in the productionof fully fertile F₁ hybrid progeny. If no restorer gene is present inthe male parent, male-sterile hybrids are obtained. Such hybrids areuseful where the vegetative tissue of the soybean plant is utilized.However, in many cases, the seeds are considered to be a valuableportion of the crop, thus, it is desirable to restore the fertility ofthe hybrids in these crops. Therefore, the disclosure provides plants ofthe new soybean variety ‘G03-1187RR’ comprising a genetic locus capableof restoring male fertility in an otherwise male-sterile plant. Examplesof male-sterility genes and corresponding restorers which can beemployed are well known (see, e.g., U.S. Pat. No. 5,530,191 and U.S.Pat. No. 5,684,242).

Modified Fatty Acid, Phytate and Carbohydrate Metabolism

Genes conferring modified fatty acid metabolism can be introduced into‘G03-1187RR’ and its progeny, such as antisense stearoyl acyl carrierprotein (ACP) desaturase genes (EC 1.14.99.6) (e.g., Knutzon et al.1992. PNAS 89:2624-2628). Fatty acid desaturases can be introduced into‘G03-1187RR’ and its progeny, such as Saccharomyces cerevisiae OLE1 geneencoding Δ9-fatty acid desaturase, an enzyme which forms themonounsaturated palmitoleic (16:1) and oleic (18:1) fatty acids frompalmitoyl (16:0) or stearoyl (18:0) CoA (McDonough et al., 1992. J BiolChem 267(9):5931-5936); a gene encoding a stearoyl-acyl carrier proteinΔ-9 desaturase from castor (Fox et al. 1993. PNAS 90(6):2486-2490); Δ6-and Δ12-desaturases from the cyanobacteria Synechocystis responsible forthe conversion of linoleic acid (18:2) to gamma-linolenic acid (18:3gamma) (Reddy et al., 1993. Plant Mol Biol 22(2):293-300); a gene fromArabidopsis thaliana that encodes an omega-3 desaturase (Arondel et al.1992. Science 258:1353-5); plant Δ9-desaturases (WIPO Publication No. WO1991/013972) and soybean and Brassica Δ15 desaturases (European PatentApplication Publ. No. EP 0616644).

Phytate metabolism can also be modified by introduction of aphytase-encoding gene to enhance breakdown of phytate, adding more freephosphate to the transformed plant. For example, see Van Hartingsveldtet al. (1993. Gene 127:87-94), for an Aspergillus niger phytase gene. Insoybean, this, for example, could be accomplished by cloning and thenreintroducing DNA associated with the single allele which is responsiblefor soybean mutants characterized by low levels of phytic acid. SeeRaboy et al. (2000, Plant Physiol. 124(1):355-68).

A number of genes are known that can be used to alter carbohydratemetabolism. For example, plants can be transformed with a gene codingfor an enzyme that alters the branching pattern of starch. See Shirozaet al. (1988. J Bacteriol 170(2):810-816) (Streptococcusfructosyltransferase gene), Steinmetz et al. (1985. Mol Gen Genet.200:220-228) (Bacillus subtilis levansucrase gene), Pen et al. (1992.BioTechnology 10:292) (Bacillus licheniformis α-amylase), Elliot et al.(1993. Plant Mol. Biol 21:515) (tomato invertase genes), Sergaard et al.(1993. J. Biol. Chem. 268:22480) (site-directed mutagenesis of barleyα-amylase gene), and Fisher et al. (1993. Plant Physiol 102:1045) (maizeendosperm starch branching enzyme II). The Z10 gene encoding a 10 kDzein storage protein from maize can also be used to alter the quantitiesof 10 kD zein in the cells relative to other components (Kirihara etal., 1988. Mol Gen Genet. 211:477-484).

Modifications can also include site-specific recombination; abioticstress tolerance; modified antioxidant characteristics; modifiedessential seed amino acid characteristics, or the like, or anycombination thereof. Merely by way of example, FRT sites and/or Loxsites can be introduced into a soybean plant. FRT sites can be used inthe FLP/FRT system. Lox sites can be used in the Cre/Loxp system.Abiotic stress tolerance can include, but is not limited to, toleranceto stress induced by, for example, flowering, ear and seed development,enhancement of nitrogen utilization efficiency, altered nitrogenresponsiveness, drought resistance or tolerance, cold resistance ortolerance, heat resistance or tolerance, low or high soil pH levelresistance or tolerance, and salt resistance or tolerance. Such abioticstress tolerance can increase yield under stress. Modifications can bemade to a soybean plant to introduce modified antioxidantcharacteristics (e.g., content or composition, such as alteration oftocopherol or tocotrienols), modified essential seed amino acidcharacteristics (e.g., increasing accumulation of essential amino acidsin seeds). Exemplary useful genes and traits for transgenic modificationof the variety are disclosed in, for example, U.S. Pat. Nos. 7,687,686,7,649,127 and 7,645,923.

Tissue Cultures and In Vitro Regeneration of Soybean Plants

Tissue cultures of the new soybean variety ‘G03-1187RR’ are provided. Atissue culture includes isolated cells of the same or a different typeor a collection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures include protoplasts, calli and plant cells thatare intact in plants or parts of plants, such as embryos, pollen,flowers, leaves, roots, root tips, anthers, meristematic cells, pistil,seed, boll, pod, petiole, stein, ovule, cotyledon, hypocotyl, shoot orstem, and the like. In a particular example, the tissue culture includesembryos, protoplasts, meristematic cells, pollen, leaves or anthers ofthe new soybean variety ‘G03-1187RR’. Also provided are soybean plantsregenerated from such tissue cultures, wherein the regenerated soybeanplant expresses the physiological and morphological characteristics ofthe soybean variety ‘G03-1187RR’.

Soybeans are typically regenerated using shoot morphogenesis or somaticembryogenesis (Finer et al. 1996. “Soybean transformation: Technologiesand progress.” In: Soybean: Genetics, Molecular Biology andBiotechnology. Verma and Shoemaker (eds). Wallinford, Oxon, UK: CABInternational, pp. 250-251). Shoot morphogenesis is the process of shootmeristem organization and development. Shoots grow out from a sourcetissue and are excised and rooted to obtain an intact plant. Duringsomatic embryogenesis, an embryo (similar to the zygotic embryo),containing both shoot and root axes, is formed from somatic planttissue. An intact plant rather than a rooted shoot results from thegermination of the somatic embryo.

Shoot morphogenesis and somatic embryogenesis are different processesand the specific route of regeneration is primarily dependent on theexplant source and media used for tissue culture manipulations. Whilethe systems are different, both systems show variety-specific responseswhere some lines are more responsive to tissue culture manipulationsthan others. A line that is highly responsive in shoot morphogenesis maynot generate many somatic embryos, while lines that produce largenumbers of embryos during an “induction” step may not give rise torapidly-growing proliferative cultures. In addition to line-specificresponses, proliferative cultures can be observed with both shootmorphogenesis and somatic embryogenesis. Proliferation allows a single,transformed cell to multiply to the point that it can contribute togerm-line tissue.

Shoot morphogenesis is a system whereby shoots are obtained de novo fromcotyledonary nodes of soybean seedlings (Wright et al., 1986. Plant CellReports 5:150-154). The shoot meristems form subepidermally andmorphogenic tissue can proliferate on a medium containing benzyl adenine(BA). This system can be used for transformation if the subepidermal,multicellular origin of the shoots is recognized and proliferativecultures are utilized. Tissue that can give rise to new shoots aretargeted and proliferated within the meristematic tissue to lessenproblems associated with chimerism.

Somatic embryogenesis in soybean is a system in which embryogenic tissueis obtained from the zygotic embryo axis (Christianson et al., 1983.Science 222:632-634). The embryogenic cultures are proliferative and theproliferative embryos are of apical or surface origin with a smallnumber of cells contributing to embryo formation. The origin of primaryembryos (the first embryos derived from the initial explant) isdependent on the explant tissue and the auxin levels in the inductionmedium (Hartweck et al., 1988. In Vitro Cell. Develop. Bio. 24:821-828).With proliferative embryonic cultures, single cells or small groups ofsurface cells of the “older” somatic embryos form the “newer” embryos.

Embryogenic cultures can also be used for regeneration, includingregeneration of transgenic plants.

Example 1 Breeding History of ‘G03-1187RR’

‘G03-1187RR’ is a F₅-derived line from the cross of G95-346 X ‘H7242RR’. G95-346 is a productive, non-glyphosate resistant (i.e.,conventional) MG VIII breeding line developed at the GeorgiaAgricultural Experiment Stations from the cross of G86-1434×G87-1968.G86-1434 originated from the cross of D79-6058×‘Twiggs’. D79-6058 hasthe same parentage as the MG VI cultivar ‘Sharkey’. G87-1968 originatedfrom the cross of ‘Thomas’×‘Gordon’. The glyphosate resistance parent, H7242RR, is a backcross-derived cultivar from the cross of{[Benning(6)]×[(Resnik(2)-RR) F2]}.

The F2 seed of Resnik(2)-RR was obtained in May 1996. Resnik is a MG IIIcultivar. The donor of the Roundup Ready® (RR) transgene that wasinitially crossed with Resnik was not known, but it can be inferred fromthe literature that the RR transgene in Resnik(2)RR was derived directlyfrom 40-3-2 or a line derived from 40-3-2 (Padgette et al., Crop Sci.35:1451-1462, 1995). The glyphosate resistant line 40-3-2 was developedby transformation of cultivar A5403 with the bacteria5-enolpyruvylshikimate-3-phosphate synthase enzyme from Agrobacteriumsp. strain CP4. The Roundup® herbicide (active compound=glyphosate) wasused in all screening for glyphosate resistance and application on seedincreases potential cultivars developed with the RR transgene.

The activities leading to the development of ‘G03-1187RR’ are outlinedin Table 1.

The initial cross was made in August 2000. The early generations wereadvanced by single-seed descent in Georgia and Puerto Rico. During thewinter of 2001, the F₁ plants were grown in the USDA Puerto Rican winternursery and during the summer of 2001 the F₂ generation was grown nearAthens Ga. The single seed descent method was used in advancing the F₃,F₄, and F₅ seed during the fall of 2001 and the winter of 2002.

During the fall of 2003 a single plant row (#1187) was selected andharvested to create the F₅—derived line ‘G03-1187RR.’ From the F₂ to F₅plants were treated with Roundup® to eliminate glyphosate susceptibleplants. Additionally, all the plant rows from this population weretreated with Roundup®. The plants in row #1187 were homogeneous forresistance to Roundup®. During the summer of 2004, ‘G03-1187RR’ wasevaluated in replicated yield plots at two locations in Georgia. In 2005‘G03-1187RR’ was evaluated at three locations in Georgia and onelocation in North Carolina. ‘G03-1187RR’ was advanced to the USDA-ARSRegional Uniform Preliminary Test V11 and grown in four locations duringthe summer of 2006. During the summers of 2007 and 2008, ‘G03-1187RR’was evaluated in the USDA-ARS Regional Uniform Test VII and the GeorgiaPerformance Test in a total of 31 environments. In 2007, 90 individualplants were harvested from ‘G03-1187RR’. During the summer of 2008,individual progeny rows of ‘G03-1187RR’ were grown and the uniform rowswere selected and individually harvested. Seed from each row wasindividually evaluated for phenotypic similarity to ‘G03-1187RR’ andscreened for southern, peanut, and Javanese root-knot nematodes and race3 of soybean cyst nematode. Seed from rows that were phenotypicallysimilar to ‘G03-1187RR’ and resistant to these four nematodes wascombined to create breeder seed.

Example 5 Production of ‘G03-1187RR’ Soybeans

‘G03-1187RR’ can be grown under normal conditions for growing soybeans,and bulk seed for large-scale planting can be obtained by methods knownin certified seed production. For example, bulk seed may be produced byplanting ‘G03-1187RR’ seeds obtained from ATCC Accession No: PTA-12952,allowing the mature plants to produce seed by self pollination with eachother and then collecting the seed. Standard precautions should be takento prevent cross-pollination from other soybeans, such as growing thevariety in an isolated plot of sterilized soil, removing adjacentvegetation, etc. The ‘G03-1187RR’ seeds deposited with ATCC are breederseeds; propagation of plants from these seeds can be performed understandard conditions known to those skilled in the art.

Example 6 Introducing Traits of ‘G03-1187RR’ into Other SoybeanVarieties

The morphological and physiological characteristics of ‘G03-1187RR’,including resistance to many pests that affect soybeans (includingsouthern, peanut and Javanese root-knot nematodes, race 3 of soybeancyst nematode, and stem canker) as well as increased seed yield, can beintroduced into other soybean varieties (such as other MG VII Roundup®Ready soybean cultivars) by conventional breeding techniques. Forexample, ‘G03-1187RR’ can be grown in pollination proximity to anothervariety of soybean, allowing cross-pollination to occur between‘G03-1187RR’ and the other variety, and then harvesting the hybridseeds. Plants grown from these hybrid seeds can then be tested for themaintenance of the characteristics described herein for ‘G03-1187RR’(such as one or more of resistance to southern, peanut and Javaneseroot-knot nematodes, race 3 of soybean cyst nematode, and stem canker,or increased seed yield), and/or the plants can simply be observed tosee if they display the same growth characteristics, seed yield, andpest resistance described in the Tables 2-10.

For example, plants grown from these hybrid seeds can be tested for anyof the morphological characteristics described herein, for improved seedyield, or for resistance to one or more of southern root-knot nematode,peanut root-knot nematode, Javanese root-knot nematode, race 3 ofsoybean cyst nematode, and stem canker. In this way, resistance one ormore of southern root-knot nematode, peanut root-knot nematode, Javaneseroot-knot nematode, race 3 of soybean cyst nematode, stem canker orincreased seed yield may be combined with other desirable plantcharacteristics. Thus, the provision of ‘G03-1187RR’ enables theproduction of progeny plants of ‘G03-1187RR’ having resistance to one ormore of southern root-knot nematode, peanut root-knot nematode, Javaneseroot-knot nematode, race 3 of soybean cyst nematode, and stem canker,and in some examples resistance to all of these. “Progeny plants” of‘G03-1187RR’ are any plants that are the offspring of a cross between‘G03-1187RR’ and any other plant or plants. Progeny plants also includesuccessive generations of the offspring, for example those selected forresistance to one or more of southern root-knot nematode, peanutroot-knot nematode, Javanese root-knot nematode, race 3 of soybean cystnematode, and stem canker, and in some examples resistance to all ofthese. First-generation progeny plants may retain the resistance tosouthern root-knot nematode, peanut root-knot nematode, Javaneseroot-knot nematode, race 3 of soybean cyst nematode, and stem cankercharacteristics of the ‘G03-1187RR’ parent. However, if afirst-generation progeny plant does not retain the desired level ofresistance to southern root-knot nematode, peanut root-knot nematode,Javanese root-knot nematode, race 3 of soybean cyst nematode, and stemcanker observed with ‘G03-1187RR’, subsequent generations of offspringcan be recycled for resistance to these pests which have at least thesame resistance to these pests as does ‘G03-1187RR’ described herein. Inone embodiment, subsequent generations of offspring can have resistanceto southern root-knot nematode, peanut root-knot nematode, Javaneseroot-knot nematode, race 3 of soybean cyst nematode, and stem canker,similar to that or or even that exceed that of ‘G03-1187RR’.

In addition, ‘G03-1187RR’ can be used as transformation targets for theproduction of transgenic soybeans. In certain embodiments, the presentdisclosure contemplates the transformation of cells derived from‘G03-1187RR’ with at least one transgene. For example, transgenes thatcan be used, include, but are not limited to, transgenes that conferresistance to one or more of herbicide tolerance, drought tolerance,heat tolerance, low or high soil pH level tolerance, salt tolerance,resistance to an insect, resistance to a bacterial disease, resistanceto a viral disease, resistance to a fungal disease, resistance to anematode, resistance to a pest, male sterility, site-specificrecombination; abiotic stress tolerance; modified phosphoruscharacteristics; modified antioxidant characteristics; modifiedessential seed amino acid characteristics; modified fatty acidmetabolism, modified carbohydrate metabolism, and modified soybean fibercharacteristics. Examples of such genes and methods of transformingplants are described in U.S. Pat. No. 6,025,545.
